A57-03 Malagasy Seafarers Spirometric Profiles in Maritime Occupational Medicine

Abstract Introduction Maritime occupational medicine spirometric profiles (SP) protects the seafarers health.The main objective was to describe the spirometric profiles of seafarers previously examined between 2016 and 2018. in the Analakininina University Hospital of Toamasina, a big harbor located on the Madagascar East Coast.Spirometry pulmonary functional test (PFT), according to the global lung function initiative ( GLI ) recommendations, was performed for assessing lung capacity and screening respiratory disorders. Methodology This was a cross-sectional, descriptive observational study of 1005 spirometry records of seafarers. Each subject underwent a pre-departure medical examination including usual spirometric parameters between 2016 and 2018., Results Our study population was predominantly male (86.7%) with a mean age of 40.5 ± 7.5 years. The mean BMI was 25.6 ± 4.0 kg/m². Smoking prevalence was 13%, with a mean consumption of 4.5 pack-years. Spirometric profiles showed that 81.4% were normal and 18.6% showed abnormalities including 10.5% with small airways obstructive syndrome and only 1.99% with obstructive ventilatory impairment. A statistically significant correlation was observed between smoking and spirometric values abnormalities, with a p-value < 0.05. 0.0001 and an OR of 12.26. Overweight and obesity were also associated with increased severity of the observed obstructive disorders, with a p-value of 0.01. Conclusion Spirometry is an essential and useful diagnostic and preventive tool in maritime medicine for the early detection of respiratory illness and for the fitness assessment for seafaring.
